A self adhering strip withcorrections thereon can then be aligned over the locations at Whicherrors occur and With the base line of the correction in properalignment, the strip can then be cut and the severed portions withcorrections applied in covering relation to the location at which theerrors occur.

BACKGROUND OF THE INVENTION Field of the invention This inventionrelates to apparatus for correcting photocomposition or cold copy bywhich self adhering strips with corrections thereon can be appliedthereto which strip is aligned, cut and the cut strip portion withcorrections thereon pressed down over the errors.

Description of the prior art In the printing industry there has been alarge recent growth in the use of phototypesetters for obtaining copy tobe used in photographically oriented printing processes. The principalinterest in connection with this invention is in the use of paper outputrather than with film or transparency output which-may also be producedby phototypesetting operations. The paper copy is pasted down into pageunits and then usually rephotographed. The presently available methodsof and apparatus for correcting errors in the printed copy arelaborious, inaccurate and slow.

One common method now employed involves superposing a strip withcorrection line over the error while the copy is held on a light table.The Word or line is cut through both layers and the incorrect portion isthen discarded. The correction is then pressed into the window obtainedby the cutting and held therein by pressure sensitive tape on the backthereof. One other method involves the use of strips with precut lineswhich are aligned over the error on a light table and then pasted down.

The results obtained were unsatisfactory in that the copy was messy, ofpoor visibility, and with incorrect alignment.

SUMMARY OF THE INVENTION Apparatus for correcting photocomposition orcold copy wherein portions of self adhering correction strips can havethe type base lines thereof aligned with the type base lines of theerroneous text. Portions of the correction copy are then cut and forceddown to cover the errors thereby providing copy that has the correctionsproperly aligned and of good visibility.

The principal object of the present invention is to provide apparatusfor correcting photocomposition or cold 3,573,138 Patented Mar. 30, 1971copy wherein the base lines of the type of the error and of thecorrection strip are aligned, so that a portion of the correction stripcan then be cut with a sharp instrument and the correction stripspressed down onto the error.

A further object of the present invention is to provide apparatus forcorrecting photocomposition or cold copy which facilitates providing anaccurate clean corrected copy.

A further object of the present invention is to provide apparatus forcorrecting photocomposition or cold copy that is simple and easy tooperate.

A further object of the resent invention is to provide apparatus forcorrecting photocomposition or cold copy that is sturdy and reliable inoperation.

Other objects and advantageous features of the invention will beapparent from the description and claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now more particularlyto the. drawings the apparatus for correcting photocomposition or coldcopy is illustated as having an outer frame with vertical side panels 10and 11, joined together at the rear thereof by a forwardly anddownwardly inclined hand hold bar 12, which is held in assembledrelation by a plurality of screws 14 engaged therewith and with thepanels 10 and 11.

Above the bar 12 each of the panels 10 and '11 is provided with a cutout portion 15 to facilitate a comfortable positioning of the hand.

At the top rear of panels 10 and 11 a bar 16 is provided with its endsset into a vertical groove 17 in each of the panels.

The bar 16 has a horizontal panel 18 movable in grooves 19 in panels 10and 11 and being adjustably movable vertically upwardly and downwardlyby adjustment of thumbscrews 20 in the panels 10 and 11. A plurality ofvertical reference or cursor lines 21 are provided on the panel 18. Ahorizontal base reference line 22 is also povided on panel 18 whoseposition may be varied, depending on the size of type to be corrected,by adjustment of the thumbscrews 20.

Below the hand hold bar 12 two rotatable advance rollers 25 are providedextending transversely and secured to the panels 10 and 11. The rollers25 are of the nonstick type and can be Teflon coated or knurled asdesired. An additional supporting roller 26 also extends transverselybelow the rollers 25 to permit of more easily positioning the apparatusat the desired location for use.

Between the panels and 11 at the front thereof a stiffener plate 27 isprovided, the plate 27 being composed of any suitable material andsecured to panels 10 and 11 by screws 28.

Below the plate 27 the panels 10 and 11 each has a triangular shapedportion 30 and 31 extending forwardly therefrom attached thereto andmounting a triangular non-stick ramp 33 therebetween, with a front edge33a. The ramp 33 is preferably composed of a porous metal impregnatedwith a silicone of well known type, however the ramp may be coated withTeflon or other suitable non-stick material as desired.

A transparent edge guide 35 is provided extending over the ramp 33 andraised a sufficient distance from the ramp to provide a clearancetherebetween. The guide 35 may be held to the portions 30 and 31 byscrews 36. The guide 35 is preferably composed of clear acrylic plastic,such as Plexiglas as made by Rohm and Haas Company, and has a frontgaging edge 35a somewhat in front of edge 33a, and extends beyond thepanel 11 to form a leg 37. This leg 37 and the indicated protrusionserve as a stop for the preferred cutter used with this invention. Aparticularly suitable cutter is shown in my prior application filed Aug.8, 1967, Ser. No. 659,077, now Pat. No. 3,448,519.

Directly above the plate 27, semi-triangular shaped panels 42 and 43 areprovided integral with panels 10 and 11 extending forwardly which haveangularly rearwardly and downwardly incline grooves 45 therein. Thegrooves 45 retain a beam splitter 51) therein which is so angularly anlinearly related to the reference lines 22 of panel 18 and the baselineof the type line 51 on the paper strips or columns .52 that theirposition is shown simultaneously and superimposed for correctionoperations.

Rearwardly of the front roller 25 an additional connecting member 53 issecured to and between the panels 10 and 11 by screws 23. The member 53is provided with a transverse slot 54 which contains an adjustable stripedge guide screw 55 for retaining the correction strip 56 in properposition, the opposite edge of the strip 56 engaging the inner face 57of the wall 11.

The mode of operation will now be pointed out.

Strips 56 with correction lines thereon corresponding to errors in acolumn of paper copy are prepared. The proper size margins are trimmedon this strip 56 and this strip 56 is then coated on the back side 'witha suitable pressure sensitive adhesive or wax. The strip 56 is thenprepared for use by threading it over the rollers 25 and between theramp 33 and edge guide 35. Initially this strip is not allowed to extendbeyond the edge 35a. The entire unit is positioned so that the image of22 as seen in the beam splitter 50 falls on the base line of theincorrect line on column 52, and the left and right hand margins of thecorrection and incorrect lines are aligned. After this positioningoperation, the strip 56 is pushed forward with the fingers pressing onthe strip over roller 25. The strip 56 is pushed forward until thecorrection line aligns with its baseline on the image of the referenceline 22. A cutter is then used to sever the line from the strip 56. Thepreferred cutter to use is one holding a blade and having a referencefoot to control the depth of cut as shown in my prior patent applicationreferred to above. This cutter is passed against the guide edge 35a tosimultaneously cut off and burnish down the correction line in theproper position.

The adjustment screws 20 are previously positioned so 4 that thereference line image of 22 is sufficiently in front of 35a so that thecut falls below the dcscenders of the type.

The apparatus is then moved along the remainder of the column 52 andother corrections are cut and pressed down as needed. The operations arerepeated until all the errors have been corrected. The apparatus can beprovided with a new strip of corrections 56 and additional columns 52corrected as required.

It will thus be seen that apparatus has been provided with which theobjects of the invention are attained.
